drm/i915: Fix GVT-g PVINFO version compatibility check

Current it's strictly checked if PVINFO version matches 1.0
for GVT-g i915 guest which doesn't help for compatibility at
all and forces GVT-g host can't extend PVINFO easily with version
bump for real compatibility check.

This fixes that to check minimal required PVINFO version instead.

v2:
- drop unneeded version macro
- use only major version for sanity check

v3:
- fix up PVInfo value with kernel type
- one indent fix
